Umm, Well, Getting back to 2.1 will not fix your problems. I would
reckon the best approach would be to re-design your UI.

 Hey Romain,

 Thanks for the reply,

 I can understand why this is not an ideal ui design - I entirely agree.  But 
 this doesn't change the fact that there seems to be some regression with the 
 Android UI code.  On researching further I've found that there are a number 
 of registered bugs for 2.2 to do with browsers exhibiting similar problems 
 whilst showing pages containing frames.  Looks like something fundamental has 
 changed here.

 As far as our use case goes - I need to be able to display whatever a user 
 requires in their screen.  Currently we can show these screens on Windows, 
 iPhone  Blackberry and Android  2.1 without any issues.  But Android 2.2 
 suddenly has this issue with the nesting.  Whilst we *could* design the app 
 to work around this bug by using a popup editor - this does not help us keep 
 things consistent, and your architecture bug free.

 As a workaround - do you know of any way to reset Nexus ones back to 2.1?

 Cheers, :)

 Peter.

 Hi,

 You should never have a scrolling widget inside a scrolling widget;
 for instance a ListView inside a ScrollView. The behavior for such a
 setup is pretty much guaranteed to not work (and definitely not
 guaranteed to work.)

  Both of these scenarios continue to work fine under 2.1, however are broken

  scrolled using the keypad.

  Has anyone else experienced this behaviour and/or have a work around??  It
  appears that the onTouchEvent function in View has been changed

[android-developers] Re: moving text effect in spinner

I am not very sure, but you can try this. Use a custom layout for your

I expect that to work, but again, have never tried that.

Re: [android-developers] Re: Handling large screens, such as tablets - still doesn't make sense to me

 The problem arises when you now get a device which still reports
 itself as HDPI, but has a much larger screen size, which is what the
 Samsung does - it reports itself as hdpi, but has 1024x600 pixels.
 What happens is your button is still 80DPI, and shows the same size as
 before, but the screen is now up to 2 times bigger in the X direction!
 Leaving either a ton of unusable space, OR still making your layout
 look small on a large screen. The problem is since android doesn't
 scale your app to fit the screen size, there is no way you can come up
 with a layout that will look proper on different screens. It may be
 functional but you wont be able to predict at all what the layout
 will actually LOOK like.


If you just want to have, say, a UI with 3x3 controls that are spread across
the available space, then tell the layout manager to this either with
weights in a linear layout or percentage units or such.  If you are using
ImageView for example for the inner controls, you can tell it how to adjust
the image to match whatever space it gets (scale it etc).


 I may still just not get this but right now it really seems
 convoluted to me. In my opinion what should have been a simple scaling
 is now a complex affair.


The behavior you are asking for is actually not what most apps want.  For
example, if I have a button in my app, I don't want its graphics to be
scaled up some fairly random amount so that whatever screen size I designed
my UI for is spread across the screen of whatever device I am running on.
 Most apps want their controls like buttons to stay the same size, and for
their UI to resize as they specify to give the extra space to a list view or
some other element of the UI that can show more data.

Or games would typically use a SurfaceView, and if they want to design their
game to assume a fixed size and let the platform resize to the real screen
size, that can be done by setting a fixed size for the surface view.  (At
the cost of potentially some jaggies or other artifacts since the entire
game in the surface view is being scaled before compositing to the screen.)

[android-developers] Re: Any way to animate a 2D Game Smooth without OpenGL ?

2010-09-15 Thread Andreas


Hi miguel,
thanks for the response.

Afaik. Every example game written by the google guys has a inner
thread class in the gameview. But i think only for sharing variables
of the gameview. Not quite sure  if there where any other advantages
gc wise.

Normally locks a more a timesink and slowing down the thread, or is
there a case where it can speed up performance. And from the normal
java world. Locks like synchronized where needed while multithreading.
Do you have more threads working on some objects?

Currently i have 1 thread running for the surface view. This thread
has a instance variabel gamedata where everything is happening. All
lists of game objects are located in the  gamedata object. Maybe this
is a archtectural flaw ?

The game view implements the touchlistener an delegates the inputs to
the thread via thread save queue. The other direction, like the thread
send a value to the score textview happens via messagehandler who
delegates the msg to the referenced views.

I think i rewrite a test project focussing on testing how i get rid of
the hiccups.

 I don't really use this myself because I don't really strings in inner loops.
 First, you want to make those time elements draw/update as least as possible.
 If not, you can use a string

[android-developers] Re: Fil-rate workaround with FBOs?

2010-09-15 Thread Samsyn

Well, I ran the experiement...

1.) it does work, though apparently the FBO texture ends up upside
down with relation to all my other textures, so I had to do a little
correction for that
2.) it does increase the frame rate, but not substantially
3.) it does look worse (a 256x256 FBO is not too awful.  128x128 is
horrid)
4.) it consumes extra memory (for the FBO buffer(s))

on a Moto Droid I, my reference scene

Without FBOs, rendering to full screen: about 20 fps
With FBOs, rendering to 128x128: about 28.5fps
With FBOs, rendering to 256x256: about 26.2fps
With FBOs, rendering to 32x32: about about 30 fps  (clearly unusuable,
of course, unless you wanted a illusion of out of focus)

512x512 is not on the table as you get an out of memory condition with
high regularity

I still have to try it on the Eris (my problem phone), but overall, I
don't think the result really justifies the feature.

I'm pretty sure the fill rate I save with the smaller render target is
lost with the render of the background quad with that texture on it.
Perhaps if I had a clever way to jam the texture (and stretch it
nicely) into the colorBuffer directly...

On Sep 12, 1:12 pm, Samsyn d...@synthetic-reality.com wrote:
 My apologies if this is a stupid question...

 Might I get a net frame rate improvement if I did something like this:

 * create an FBO of resolution less than the full phone screen
 dimensions (user-selected quality vs speed option)
 * do most of my scene rendering into that FBO
 * then the 'real' (full screen) render would either use the FBO as the
 starting background color buffer contents, or render it (probably
 orthographically) as a single quad.
 * then probably add UI/Text decoration on top of that, where the
 resolutions really benefits.

 And, is there some egl glue (I am a glSurfaceView kinda dood) that
 would automagically do something like this in the first place?

 Or am I being naive to think the GPU could do its work faster if it
 was rendering to a lower resolution target?

 And would the phone with the worst fill rate also be the phone that
 doesn't support FBOs in the first place?

 After reading the OpenVR info (thanks again, Lance) I think I might
 get some improvement by breaking some huge triangles into smaller
 ones. I have some (water layer, in particular) that are so large they
 probably get processed by every tile of the screen.

 Thanks for any insights,

[android-developers] Problem with broadcasts and permissions

2010-09-15 Thread Heiko

Hi,

I have two applications, one of which (B) implements a broadcast
receiver. The application (A) which sends the broadcast, binds a
permission to it which the receiver (B) shall possess. The problem is
now: If I install the receiver (B) first and the sender (A)
afterwards, the receiver will never receive the broadcast.
I assume this happens because the installation of the receiver
somewhere fails when it comes to the uses permission part of the
manifest (because this permission is not yet registered/defined).
However, this issue should be resolved as soon as the sender (which
defines the permission in the manifest) is installed, but
unfortunately isn't.

It does not even help to re-install the receiver. The only way to
resolve the issue is to completely uninstall the receiver application
and do a fresh install.

Is this behaviour intended (not a bug, a feature)?

Cheers,
Heiko

  Thanks for writing in. We are currently investigating this issue. So far,

This fits, actually.

Hi,

I'm trying to understand the layout engine for different screen sizes
and densities, to look into adding support for tablets in my apps.

I was under the impression that you could also have different layouts
based on screen density as well in android, and it would select the
appropriate one.

I have the following:

a layout-normal-mdpi directory with a layout.xml file.
a layout-normal-hdpi directory with a layout xml file with a different
layout for high density screens.

In my application manifest I have min SDK as 3, target SDK as 5. I
have a supports-screens element and declare the following:

android:largeScreens=true android:anyDensity=true

I'm compiling against Android 2.2 library.

However, when I run an AVD that is in WVGA854 mode with a lcd.density
of 240, android isn't using my hdpi layout, it still uses my mdpi
layout. I don't know why and need help!

Thanks!

[android-developers] Re: Scrolling broken in 2.2 ?

It sounds like Peter is working on so,e framework for cross platform
applications, si it's probably less than ideal to make Android just
act different.

You are probably out of luck for 2.2 if the browser exhibits the same
behavior.

  Hey Romain,

  Thanks for the reply,

  I can understand why this is not an ideal ui design - I entirely agree.  
  But this doesn't change the fact that there seems to be some regression 
  with the Android UI code.  On researching further I've found that there are 
  a number of registered bugs for 2.2 to do with browsers exhibiting similar 
  problems whilst showing pages containing frames.  Looks like something 
  fundamental has changed here.

  As far as our use case goes - I need to be able to display whatever a user 
  requires in their screen.  Currently we can show these screens on Windows, 
  iPhone  Blackberry and Android  2.1 without any issues.  But Android 2.2 
  suddenly has this issue with the nesting.  Whilst we *could* design the app 
  to work around this bug by using a popup editor - this does not help us 
  keep things consistent, and your architecture bug free.

  As a workaround - do you know of any way to reset Nexus ones back to 2.1?

  Cheers, :)

  Peter.

  Hi,

  You should never have a scrolling widget inside a scrolling widget;
  for instance a ListView inside a ScrollView. The behavior for such a
  setup is pretty much guaranteed to not work (and definitely not
  guaranteed to work.)

[android-developers] Re: Cant seem to get resources to select with layouts for different densities

2010-09-15 Thread niko20

Ok - one more question

In my project I set the layout UI designer to Nexus One. This
allowed me to create a layout based on a long screen such as a Nexus
one.

However, even with that, when I run it on a WVGA845 it still doesn't
look right since the screen is still 85 pixels wider than a Nexus one!

I guess I need to switch to all Relative Layouts or something - but I
still dont see how you can ever get a layout that isn't going to look
funky on different screen dimensions.

Is it suppose to work this way?

I have a TabActivity with 3 tabs, each tab started an activity and I
realise when a tab is clicked onResume is call. If I have onCreate,
when app start it will launch onCreate and then onResume immediately.

So, I can just get ride of onCreate in this case?

[android-developers] Re: ADT master version

2010-09-15 Thread Indicator Veritatis

Do I really have to explain something so elementary? 8 is not the
same as 8.0.0 is not the same as 8(.0.0). So yes, you did make it
more confusing instead of less.

For that matter, are they sharing the same version number, or the same
API level? The version number is 2.2, the API level 8. Based on what
you have said so far, it sounds like you are using the API level as
the version number for the tools, which is not the same as making all
tools and plug-ins share the same version number.

So again, yes, you are making things more confusing instead of less.

Well, it depends on how many different frequency bins he wants and how

Otherwise, he can get a lot of mileage out of an FFT algorithm even in

Some questions:

1) since you say the file does not open, I assume you are landing in
the catch{} clause with an exception. What exception do you get?
2) what Activity do you have registered for
android.content.Intent.ACTION_VIEW in AndroidManifest.xml?
3) How did you arrive at the conclusion that filePath + / +
label.getText() was the right way to build the file name? That looks
like path + extension w/ everything in between missing.

 Theoretically, this code should find the extension on the file, then

[android-developers] Intent filter to launch an application

2010-09-15 Thread Alok Kulkarni

Hi,
I want to do  the following.
When a user clicks on a URL containing a few specific keywords like
http://ad.mysite.com from somewhere like entering the URL in a to do
note in calendar, i want to recognize mysite.com keywords and launch
my application instead of browser.
I know that the browser activity's manifest file contains a filter to
launch it if the keywords http or www are found .So how can i override
this behaviour?
Thanks,
Alok.

[android-developers] Re: Is anyone's active install % dropping like a rock lately?

2010-09-15 Thread Droid

If you put an update out it tempts a few (me usually) to
uninstall the App - I usually figure that its not worth my  time
updating it
and I do not want it to auto update incase it installs a nasty, so I
delete it
and figure I can always get it when I want it again.

   Thanks for writing in. We are currently investigating this issue. So far,
   this appears to be purely a reporting issue: some update events are being
   inaccurately recorded as uninstalls, rather than updates, creating a 
   lower
   active installs percentage. However, our investigation tells us that
   applications are not actually being uninstalled. We hope to have a
   resolution soon.

 This fits, actually.

 I had been holding steady at around 50%. Released my first update for
 a month
 yesterday evening and now I'm down to 45%.

[android-developers] Easiest way to know if SD card has been prepared?

2010-09-15 Thread HaMMeReD

How would one know if the SD card has been mounted at startup.

Perhaps some sort of callback/event/message that I can grab that tells
me when SD has been mounted/unmounted?

My LWP starts before SD is available, but can check for add-ons that
are on the SD card. I need to delay load until after it is ready when
there is a dependency.

Thanks in advance,
 Adam

[android-developers] Re: How to create a common library in android - containing resource files as well

2010-09-15 Thread DanH

As I understand it, the common library stuff is broken, since you
can't put any UI stuff in the library due to naming problems.  There
was a thread on this topic a week or two back.

String, I think that hijacking mostly occurs when someone uses an
email reply to start a new thread.  It's a bit of ugliness in the
Google Groups implementation, and only partly the fault of the poster.

[android-developers] Why I can not open database in my service layer class

2010-09-15 Thread xi developer

When I create a instance of the SQLiteOpenHelper, I always need a
Context to be passed as its constructor's argument. To use this
Context, in my service layer class, I extends Activity class, though
I do not display this activity on the screen because it is my service
layer. I always get NullPointer exception when I open the
SQLiteOpenHelper in my service layer class, Is it because my service
layer class extends the Activity class but I did not show this
activity on mobile screen? (That's there is no intent to my service
layer class), if it is so, how to get rid of it if I wanna open a
SQLiteOpenHelper in my service layer class which do not need to
extends Activity, but need a Context object to pass to
SQLiteOpenHelper?

You're sure the other statements are being hit? (Breakpoints or logging will
tell you that.

Is the value actually changing, just taking a second or two? I assume sensor
data will be triggered frequently and Toast messages get queued up, so what
you might be seeing is not the first message permanently, but multiple
instances of the first message. If you wait long enough it should change.

That said, Toast is probably not the best way to display changes in sensor
data.

Right. That's how it works.

Don't wait 30 - 40 minutes to reuse your app?
If you haven't used an app this long, it's reasonable to expect it to be
killed and started from scratch next time you open it. Why is this a

[android-developers] Race condition (?) in Dialog causes NPE?

2010-09-15 Thread Zsolt Vasvari

Hello, I have a custom widget that can display a pop-up dialog.  I
have a single report of a NPE happening, and looking through my code,
I don't know how that's possible unless there is a race condition
involved somehow.  Just wondering if anybody can point me to the
problem.

Here's my code (irrelevant stuff omitted):


public class CurrencyEditText extends LinearLayout
{
Dialog  mDialog;   // If the dialog is NOT showing, this is NULL

protected void onDetachedFromWindow()
{
super.onDetachedFromWindow();

// Dismiss, if showing
if (mDialog != null)
{
mDialog.dismiss();
mDialog = null;
}
}

private void showDialog()
{
Builder builder = new Builder(context);

// Set dialog properties, omitted...

builder.setPositiveButton(R.string.set, new
OnClickListener()
{
public void onClick(DialogInterface dialog, int
buttonId)
{
// Dismiss
CurrencyEditText.this.mDialog.dismiss();
CurrencyEditText.this.mDialog = null;

// Send message here, omitted...
}
});

builder.setNegativeButton(android.R.string.cancel, new
OnClickListener()
{
public void onClick(DialogInterface dialog, int
buttonId)
{
// Dismiss -- NPE happens on next line as mDialog
is NULL, which it shouldn't be
CurrencyEditText.this.mDialog.dismiss();
CurrencyEditText.this.mDialog = null;

// Send message here, omitted...
}
});

mDialog = builder.show();
}
}


That's it -- mDialog is not touched anywhere else.  So either the
click listener is called after onDetachedFromWindow() or before
builder.show() can set mDialog.

Obviously, I could address the symptom by butting a NULL check around
the crashing line, but I would like to understand what's going on here
as I use the same pattern all over my app.

Thanks.

[android-developers] Re: How to get image from received share intent from Gallery

Well, You get the content Uri, query the MediaStore content provider
with this Uri, and you will get the absolute path to the image from
the column called data. Do whatever you want with this.

But, this doesn't seem to work on all platform releases, especially,
the behaviour is different on devices lower than and 1.6 and later.

The Android bug tracker has a long running bug regarding this.
http://code.google.com/p/android/issues/detail?id=1480

If you are tagetting devices with 1.6 or before, you probably have to
find something else.

[android-developers] Re: Any way to animate a 2D Game Smooth without OpenGL ?

2010-09-15 Thread Jason

Hi Andreas,

Sorry to jump in late, but I thought I'd share my experiences with non-
opengl on Android.

I have a game engine which uses both open gl and the canvas system
depending on the device capabilities (some devices, like HTC Tattoo
have software implementations of opengl which is actually slower than
canvas).  I get reasonable performance from the canvas api, but the
important thing is that the bottle-neck has always been draw speed and
nothing else.

I pretty much followed the replica island approach whereby I have two
threads, one which just draws and the other where all the game calcs
are done.  My game thread routinely outperforms my render thread, but
I am drawing quite a lot so this may not be everyone's experience.

I'd say you do have a slight architectural flaw in that (it appears)
that your game logic is being computed in the same thread as the
rendering.  This means that the render thread has to wait each frame
for the game to update state.  It's much better to separate these
two.  Have your game logic updated in a separate thread, then just
notify the render thread when it's time to draw (you can do this by
sending a message to your surface view using a Handler and then
invalidating the canvas).

Basically what I do is this:

I have a separation of game objects, and renderable objects.  A game
object is the real representation of the in-game element (eg the
player).  The renderable object is simple a set of x,y coords, plus
scale, rotation etc and a reference to the image that represents the
sprite (I have some more logic to include sprite animations etc, but
the basic concept is the same).  Hence my renderables are dumb.
They don't know what they are, they just know how to be drawn.  My
game objects contain all the important logic information (eg player
health etc).   This is how I cater for both Canvas and OpenGL.  I have
CanvasRenderable objects and OpenGLRenderable objects which both
extend a common base class (... you guessed it.. Renderable).  This
base class pretty much has just one method... draw().  (actually it
sends in a reference to the graphics context... so either Canvas or
GL10, but you get the idea)

When the render thread is drawing the renderables, the game thread is
processing the next step in the game.  Once the game thread has
completed its step, it waits for the render thread to complete (I
implemented a simple mutex sort of like the java ReadWriteLock, but
one that doesn't allocate a bunch of objects like the ReadWriteLock
does!).  Once the render thread has completed, I send all the updated
coordinates, rotations etc to the renderable objects from the game
object counterparts.  While I am doing this, I prevent the render
thread from rendering the next frame (using the same mutex) so it
isn't rendering objects in a half-moved state.

Then the game thread is ready to process its next step, and it uses
the time taken to process the last step (including the time spent
waiting for the render thread) as the input into the calculations.

The end result is that the render thread is just doing one thing..
rendering... as fast as it can.  All the actual logic is separated
into the Game Thread.  The only delay in each frame is the time it
takes to set all the coordinates etc on the renderables.. which is
usually pretty fast.

The third thread is just the Activity which handles the user input
etc.  This will typically only affect objects in the Game Thread (eg
increase speed of player etc)

As far as GC calls go, I have not been able to eliminate them
completely (there still seem to be allocations buried in the Android
api which I can't seem to get rid of) but they are infrequent enough
that it's not really an issue.  I just used the Allocation Tracking to
locate any dodgy allocations and re-code them out.  I'm currently not
rendering any Strings however (not during gameplay anyway), but you
could also get around this by not writing text as such, but by simply
drawing each character as an image.  So you have a small image for
each alpha-numeric character you need, then maintain a fixed size
array of values representing the String you need to draw.  Then you
just draw a sequence of images.  Of course you would abstract this so
it makes your life easier (eg create a renderable which takes a
numeric value and knows how to draw it as a sequence of images at an
x,y position).

I assume you have already done so, but if not I strongly recommend you
watch the YouTube video of Chris Pruett explaining his game
architecture.  Made a lot of sense to me.

http://www.youtube.com/watch?v=U4Bk5rmIpic

Not sure if I've really been any help here, but if you have any
questions I'd be happy to share whatever I have learnt (so far).

Cheers,

Jason.

The code you posted adds 10 RBs to a group. Then your get function returns a
new one that's not associated with anything. How do you expect that to work?
You're basically saying, when getting a Radio Button, instead of getting
one I already created, make a new one and if was trying to get the first
one, set it to checked. Also, don't associate it with a group so its checked
state won't effect others.


  2 - You're using getApplicationContext().

 I have try with just this instead of getApplicationContext(), but the

This won't fix your problem (see #1), but you should avoid
getApplicationContext(). It will cause you problems elsewhere.

Should I use something else ?


Your most local Context ... usually this.

Also, I've not yet learned how to do data any other way than XML

putting this out on the internet somewhere and not bundling with the

 problem?

My app based on maps and blogs, many of users said that isn't
convenient when they hide an app, and restating it to startup
activity.

They want that app coming to the same activity.

For example, you are reading blog, and meet your friend somewhere, you

[android-developers] Use of FLAG_ACTIVITY_SINGLE_TOP and FLAG_ACTIVITY_CLEAR_TOP

2010-09-15 Thread Shekhar

Hi,

I am facing a problem with the launch of activity mode as
SingleTop.I have four activities A,B,C,D which are declared as
SingleTop.Also I have a activity X from which these activities are
launched.X is declared as SingleTask.

Now the use case scenario is:

I launch activity X and from there activity C.From Activity C  goto
activity Y and there press the Home key and got the home screen and
from there again launch
activity X and then C. To launch C , I have use the flag

intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP |
Intent.FLAG_ACTIVITY_CLEAR_TOP);

But observed that instead of launching the same instance , first
onDestroy() of C gets called followed by onCreate() of
Activity C which is not as per my expectation. I expect that
onResume() will be called for activity C.

Am I doing anything wrong or this is the desired behavior?


Note: I have not implemented onNewIntent() API in my class.

Thanks,

Either play with Activity launch flags (I doubt there's something that will

[android-developers] Re: able to select 2 RadioButton in a RadioGroup ??!??!

 The code you posted adds 10 RBs to a group. Then your get function returns a
 new one that's not associated with anything.

hu ? the only radio button I add are the one returned from the
function :

group.addView(getRadioButton(i));

it is equivalent to the following code (which doesn't work either) :

for (int i = 0; i  10; i++) {
RadioButton v = new RadioButton(this);
if (i == 3) {
v.setChecked(true);
}
group.addView(v);
}

 You're basically saying, when getting a Radio Button, instead of getting
 one I already created, make a new one and if was trying to get the first
 one, set it to checked. Also, don't associate it with a group so its checked
 state won't effect others.

 This won't fix your problem (see #1), but you should avoid
 getApplicationContext(). It will cause you problems elsewhere.

 Should I use something else ?

 Your most local Context ... usually this.

[android-developers] Re: UI is blocking on IntentService

2010-09-15 Thread Bret Foreman

A little more study of this behavior is making me suspect that the
problem is not the UI getting blocked but that the IntentService
thread is hogging the CPU. It shouldn't be doing that (Unless the
HttpPost is doing something stupid like polling a register) but I
think I'll roll out some profiling just to make sure.

[android-developers] Re: able to select 2 RadioButton in a RadioGroup ??!??!

@Treking,

You will have to create new Radiobuttons each time, else, you will not
be able to add it to the RadioGroup. It will say, the child already
has a parent. So, if you want to display multiple radio buttons like
this, then, you have to create new ones, i.e, you cannot reuse that.

There seems to be a problem, if you try to set the checked option,
before adding it to the RadioGroup. If you set it after adding it,
that works fine...

Here's the code.

RadioGroup rg = (RadioGroup) findViewById(R.id.RadioGroup01);
for (int i = 0; i  6; i++) {
rg.addView(getRadioButton(i));
}

((RadioButton)rg.getChildAt(0)).setChecked(true);

private RadioButton getRadioButton(int index) {
RadioButton rb = new RadioButton(this);
rb.setText(Radio  + index);
return rb;
}

[android-developers] Re: Easiest way to know if SD card has been prepared?

I guess, you can also check for Broadcasts, if you mount-remount your
sdcard frequently when your application/service is running.

But, checking for the storage state is the surest way.

 Environment.getExternalStorageState().

[android-developers] Re: able to select 2 RadioButton in a RadioGroup ??!??!

You have to create a new RadioButton each time. Else, trying to re-use
the one radio button which is already added to the radio group, will
throw an error.

Setting the Radio Button before adding it, has this problem. If you
set the radio button after adding it to the radio group, it works
fine.

RadioGroup rg = (RadioGroup) findViewById(R.id.RadioGroup01);
for (int i = 0; i  6; i++) {
rg.addView(getRadioButton(i));
}

((RadioButton)rg.getChildAt(0)).setChecked(true);

private RadioButton getRadioButton(int index) {
RadioButton rb = new RadioButton(this);
rb.setText(Radio  + index);
return rb;
}

[android-developers] Re: Race condition (?) in Dialog causes NPE?

2010-09-15 Thread Mark Carter

Do you have access to the stacktrace?

On Sep 15, 3:29 pm, Zsolt Vasvari zvasv...@gmail.com wrote:
 Hello, I have a custom widget that can display a pop-up dialog.  I
 have a single report of a NPE happening, and looking through my code,
 I don't know how that's possible unless there is a race condition
 involved somehow.  Just wondering if anybody can point me to the
 problem.

 Here's my code (irrelevant stuff omitted):

 public class CurrencyEditText extends LinearLayout
 {
     Dialog  mDialog;   // If the dialog is NOT showing, this is NULL

     protected void onDetachedFromWindow()
     {
         super.onDetachedFromWindow();

         // Dismiss, if showing
         if (mDialog != null)
         {
             mDialog.dismiss();
             mDialog = null;
         }
     }

     private void showDialog()
     {
             Builder builder = new Builder(context);

             // Set dialog properties, omitted...

             builder.setPositiveButton(R.string.set, new
 OnClickListener()
             {
                 public void onClick(DialogInterface dialog, int
 buttonId)
                 {
                     // Dismiss
                     CurrencyEditText.this.mDialog.dismiss();
                     CurrencyEditText.this.mDialog = null;

                     // Send message here, omitted...
                 }
             });

             builder.setNegativeButton(android.R.string.cancel, new
 OnClickListener()
             {
                 public void onClick(DialogInterface dialog, int
 buttonId)
                 {
                     // Dismiss -- NPE happens on next line as mDialog
 is NULL, which it shouldn't be
                     CurrencyEditText.this.mDialog.dismiss();
                     CurrencyEditText.this.mDialog = null;

                     // Send message here, omitted...
                 }
             });

             mDialog = builder.show();
     }

 }

 That's it -- mDialog is not touched anywhere else.  So either the
 click listener is called after onDetachedFromWindow() or before
 builder.show() can set mDialog.

 Obviously, I could address the symptom by butting a NULL check around
 the crashing line, but I would like to understand what's going on here
 as I use the same pattern all over my app.

 Thanks.
